The command bootefi calls efi_init_obj_list to do the efi set up before launching an .efi payload, but efi_init_obj_list is called only once. There are some initializations which depend on the environment and should be done each time a payload gets launched and not only once and can now be done in efi_start_obj_list(). A motivation for this change is the following order of events:
1. Launch an EFI application (e.g. bootefi hello) 2. Change the ip address 3. Launch another application which uses the pxe protocol
As the EFI pxe protocol was initialized when the handles for efi net were created in 1., the ip was hardcoded there.
In this example, another possibility would be to make a callback for ip address changes to go all the way up to efi_net.
